[PATCH] nfsiostat: restore output format

[Weston Andros Adamson <dros@netapp.com>]

recent changes to support python 3 changed the output of nfsiostat from:

read:             ops/s            kB/s           kB/op         retrans         avg RTT (ms)    avg exe (ms)
                 48.094         2889.133         60.072        0 (0.0%)         177.160         184.833
...

to:

read:
  ops/s		   kB/s		  kB/op		retrans		avg RTT (ms)	avg exe (ms)
		  0.000
	  0.000
	  0.000
       0 (0.0%)
	  0.000
	  0.000
...
